If you've been using Google Drive on your mobile device, there may have been times when you wanted to make an edit to a spreadsheet but weren't able to do so. Well, you can now. Today Google rolled out an update to its Drive app for Android and iOS that enables you to edit your spreadsheets to your heart's content.

While many Google fans speak highly of the web giant’s Google Drive features, it’s been something of a bugbear for mobile users that the spreadsheet facility has up to now been limited to viewing only.

The good news is that an update to the Android and iOS Drive app rolled out on Wednesday now allows anyone using it on their iPhone, iPad or Android device to make edits to spreadsheets, as well as carry out a number of other functions.

The new feature brings it in line with Drive’s Docs offering, which was enabled for editing via the app a couple of months back.

“From the Drive app on your iPhone, iPad or Android device, you can create a new spreadsheet or edit an existing one,” Google said in a post about the update. “You can switch fonts, resize columns, sort data, and more. And just like on your computer, you’ll be able to see other people’s edits in real time as they’re made.”

Other changes to the update introduced with version 1.2 of Google Drive include improved text formatting when copying and pasting in a Google document.

Android users will now be able to edit text within tables in documents as well as add a shortcut on the homescreen of their mobile device to any of their files in Drive.

Here’s the full list of the new features as detailed on Google Play:

- Edit Google spreadsheets in new native editor

- Edit contents of tables in Google Docs editor

- Formatting is maintained when copy/pasting within Google Docs

- Single tap to enter edit mode in Google Docs editor

- Add a shortcut to Drive files/folders to your homescreen for quick access

- Send Link now supports copying link to clipboard

In other Google Drive-related news this week, it was announced that Gmail users can now attach files of up to a whopping 10GB by hosting them on Drive. Before, attachments were limited to what now sounds like a very measly 25MB.

Android users interested in trying out the free Google Drive app can pick it up from the Google Play store here. iOS users can grab it from the iTunes store here.

HTC has appointed a new chief marketing officer in a bid to turn its dwindling market share around. It's planning an entirely new strategy, dubbed Marketing 2.0 internally, which will be implemented next year.

HTC knows it has got to do something about its position in the market, which has been steadily declining ever since Samsung became de facto king of the Android smartphone. Its plan involves a marketing blitz, which it has named Marketing 2.0 internally, as it has obviously found out being “quietly brilliant” just isn’t enough.

To herald this new beginning, HTC has appointed Benjamin Ho as the new head of Marketing, and he will join the company in January. Former marketing boss John Wang will leave the company, while Jason Mackenzie — who has been looking after marketing and sales strategy — will now solely focus on sales.

Ho comes to HTC from Far EasTone Telecommunications, where he was VP of Business Strategy and Marketing and prior to this, he was CMO at Motorola Asia. When he arrives at HTC, his first project will be Marketing 2.0, which according to HTC is designed to “refocus [the company’s] efforts around holistic marketing and mass-market brand outreach.” Just in case you don’t speak Marketing Fluff, this means HTC wants a broader, everything matters strategy, presumably feeling its current approach is too niche or abstract.

HTC has captured business headlines recently due to its poor financial performance, having posted a fourth consecutive loss during the third quarter of this year. According to Interbrand, HTC’s brand value has fallen by 24-percent this year, but it remains the number one Taiwanese brand name, beating Acer and Asus. Samsung, however, was listed as one of Interbrand’s top rising brands of 2012, gaining 40-percent brand value over the previous year. The Korean firm has also been linked with a rebranding project, set to be revealed during CES 2013, but it may not be as grand as many initially thought.

As for HTC, it has signed a joint patent licensing deal with Apple, is still hanging on to fifth position in IDC’s global smartphone market share report and has recently launched the exciting Droid DNA with Verizon. It’s not all doom and gloom, so maybe a new marketing play will help turn things around in 2013.

After months of silence, Microsoft has spoken about the Windows Phone 7.8 update, confirming that it's still being worked on and that it's scheduled to arrive early next year.

Microsoft has finally provided a few more details on Windows Phone 7.8, the update designed to appease Windows Phone 7 device owners who won’t be receiving an upgrade to Windows Phone 8. However, although the news confirms it’s still being worked on, there’s no exact launch date.

Windows Phone 7.8 was announced alongside Windows Phone 8 in June, but when the new software was released at the end of October and Microsoft did not mention it at all, we questioned what was going on. Microsoft promised new information “in the coming weeks,” and here we are.

Terry Myerson, Corporate Vice President of Windows Phone, has now covered the topic on the official Windows Phone Blog. We already know WP7.8 will bring the new Start screen to older devices, but now we also know it will feature new themes and 20 different accent colors, plus the chance to make the Bing Picture of the Day your lock screen image. Microsoft has also provided some extra security with a new passcode system too.

If you’ve been following the Windows Phone 7.8 story, then you’ll recognize most of these features from a late-October leak, however there has been no confirmation of Xbox Music, SmartGlass or the possibly Lumia-specific Bluetooth media transfer feature.

So when is it coming? If you’re heading out to buy a new Windows Phone 7 device, which Nokia still produces, then in the near future it should come with Windows Phone 7.8 already installed. Myerson explains that these cheaper devices are “incredibly important for broadening the reach of Windows Phone across the globe.”

As for the update, it’s not coming until “early 2013,” confirming Microsoft’s split strategy rumored in mid-November. So, that’s a five month wait between announcement and now, plus at least another month until it’s even slightly likely to appear? That’s pretty slow, Microsoft. The post says it’s working with networks and hardware partners to get the update approved, so it can be on as many devices as possible early next year. How early is early? Only Microsoft knows, but with the Apollo Plus Windows Phone 8 update rumored to be up for discussion at Mobile World Congress 2013 — which begins on February 25 — it’s logical to expect more information then.
