Twitter Jumps on Photo Filter Bandwagon
Not to be outdone by Instagram, Twitter has added photo filters to its iOS app. Twitter version 5.2 brings eight different filters, the ability to crop and scale images, and an easy to use grid view for finding the best looking filters for your photos.

Earlier this month, Instagram decided to disable the ability to properly display images on Twitter. Twitter users are now forced to visit Instagram’s website to correctly view images posted via the Instagram app. Instagram’s chief executive, Kevin Systrom said in an interview: “We’ve decided that right now, what makes sense, is to direct our users to the Instagram website".
Tapbots: Don't Panic! Twitter's New Rules Won't Tap Out Tweetbot
The makers of Tweetbot reassured their users that Twitter's new rules for developers won't affect Tweetbot for Mac or iOS devices.
Twitter made it harder for third party clients by announcing stricter guidelines about how the Twitter API is used. Paul Haddad broke down the API changes and what the mean to Tweetbot on the Tapbots blog.

Haddad said Twitter's required authentication on every API endpoint won't affect Tweetbot, and could possibly be helpful.
"The new rate limits that are part of the v1.1 API will likely end up being a good thing, instead of having a fixed block calls that can be made across the entire API the limits will be based on specific actions. We actually expect this to minimize the chances of being stuck in 'Twitter Jail'."

Use Siri to Update Facebook and Twitter on iPhone 4S (No Jailbreak)
Siri has been receiving lots of attention lately from iPhone 4S owners looking to expand her capabilities. There are more tweaks and customizations arriving every day from developers in the jailbreak community. Of course, there are still things you can teach Siri to do without jailbreaking your iPhone 4S.
Although Apple has not included support for Siri to update social networking sites such as Facebook and Twitter, you can easily set up your iPhone 4S to make this possible. Siri will then take your commands and upload the message directly to your account. The same trick can even be used to let Siri update Google+ as well.
Use Siri to Update Twitter With Sireet iPhone Tweak
Now that the iPhone 4S has been jailbroken developers are scrambling to provide new tweaks and improvements to enhance iOS 5. The Siri personal assistant is exclusive to the iPhone 4S and is already getting some great enhancements to add functionality. One example of a feature left out by Apple is the ability to update Twitter with Siri.

Apple still considers Siri technology in a beta phase, which is probably one reason why sending tweets is not officially supported. Not only this, but iOS 5 is the first time Apple has integrated Twitter into the operating system. Now thanks to Sireet, jailbroken iPhone 4S users can natively send tweets using Siri.
iOS 5.1 Shows Apple May Integrate Facebook After All
Rumors of Facebook integration on future iOS devices has been floating around for some time, with previous reports pointing to Facebook joining Twitter in the initial iOS 5 release. Although this was not the case, code in the iOS 5.1 beta 3 firmware seeded to developers shows that Apple continues to work on system-wide Facebook integration.
iMore has found evidence of Facebook references that could mean Apple will add this functionality in iOS 5.1 or another future release. The site explained that Facebook was expected to be integrated into iOS devices with the iOS 4 firmware launch, but Apple and Facebook couldn't agree on terms for the deal.
Has Apple Integrated Facebook Into iOS 5?
Apple watchers have long known that the company integrated social networking service Twitter into its next generation mobile operating system iOS 5. What remains to be seen is whether or not Facebook will join Twitter and enjoy its own iOS 5 integration on iPhones and iPads. The screenshots below are from MacRumors however the site couldn't vouch for their authenticity.

For one thing, the word addresses is spelled wrong which points to these being a simple mockup or someone's independent dream. On the other hand, with Twitter hitting iOS 5 full force it's hard to imagine that Facebook doesn't want a piece of this attention from Apple users. Not only this, but Facebook is strangely said to be planning an iPad app announcement on the same day that Tim Cook is scheduled to announce the next generation iPhone.
