As I wrote earlier today, an update to the official Twitter app for iPhone and iPad was one of the updates I was really looking forward to. We knew the new version had been approved by Apple, and it was just waiting to go live in iTunes. The update, version 3.2, is finally available here.

As announced on the official Twitter blog, push notifications for messages and mentions have been enabled in the app. They’re available only on the iPhone counterpart for now:

When you’re out and about, your phone probably isn’t always in front of you. It might be in your pocket or purse or on a table – perhaps with the screen off. We want to make sure you see important Tweets even when you’re not looking at Twitter at the moment. To help with that, today we’re launching push notifications for mentions.

In addition to mentions, we’re also bringing push notifications for Messages to Twitter for iPhone, as we’ve already done with SMS and Twitter for Blackberry.

The update also brings more Retina graphics to the iPhone and geotagging with “one tap”. But the real deal’s on the iPad: we’re installing the updated version right now, but looking at the changelog we see Loren Brichter has been working on bringing inline media to the app, together with lots of UI improvements, iOS 4.2 fixes and saved search management.

These improvements include a simpler way to dismiss “panels” opened while navigating between users and links, more intuitive behavior for the aforementioned panels and various fixes to improve the user experience. It’s easier to navigate back to the first panel (or, the “timeline”) now, the animation of inline web previews has been slightly tweaked to “bounce” more when swiping and you can swipe on the inline media viewer, too. The effect is cool, but I wonder what’s the purpose. Try it by yourself with any twitpic or yfrog link.

As for iOS 4.2 support, the app correctly saves states and the login error that affected the previous version on iOS 4.2 has been fixed.

Fullscreen.me is a neat service I discovered last night which enables you to create iOS web apps that run in full-screen mode with just a few taps. Many popular web services out there come with iPhone and iPad specific interfaces (Gmail, Google Reader, Flickr), but wouldn’t it be great to easily run them in full-screen mode instead of being forced to open them in Mobile Safari every time you launch a webclip?

Fullscreen.me does just that: it turns websites into full-screen web apps. You can choose from a set of built-in services (namely Google products) or manually enter a URL and make your own web app. What’s cool is that Fullscreen.me lets you pick your own icon (stored somewhere on the internet) to override a website’s default apple-icon.png – meaning no more fuzzy Gmail icon on your Springboard. You can also set a custom status bar color or create a “splash URL” to display before the web app fully loads.

You can try out Fullscreen.me by opening it on your iOS devices. Really good stuff.

As we previously reported, Apple just released a second GM build of iOS 4.2 for iPad to deal with the WiFi issues. It’s available in the iOS Developer Center. Build number is 8C134b, and it’s a 551MB download.

This build is meant to address the WiFi issues experienced by several users. From what we’re hearing, Apple wants to get testing done as fast as possible – iOS 4.2 might drop next week.

Apple didn’t change the date of the original GM build, you’ll still see “November 1” on the dev center. The iPad build, however, is new.
