After three weeks of iOS 5 beta 1 release Apple today seeded iOS 5 beta 2 for developers only. iOS 5 Beta 2 Build 9A5248d is now available for download in Apple developers portal. Do not download it from any other external links as you won’t be able to activate your device and no trick is working to activate it till now.

WiFi syncing is now active in iOS 5 beta two you can sync your device with iTunes over WiFi, but you’ll also be needing iTunes 10.5 beta which also has been seeded and is available in developers portal.

In iOS 5.0 beta 2, wireless syncing is now available for the Mac. It requires iTunes 10.5 beta 2 and OS X 10.6.8 or Lion. You will see an option to enable wireless syncing when you connect your device to iTunes with the USB cable. It is recommended you perform your initial sync with a cable after restoring your device.
Wireless syncing is triggered automatically when the device is connected to power and on the same network as the paired computer. Or, you can manually trigger a sync from iTunes or from Settings -> General -> iTunes Sync (same network as paired computer required). Be sure your device is plugged into a power source when performing Wireless syncs.

After restoring  iOS 5 beta 2 firmware, a new animation will welcome you as the device turns on displaying the Apple logo, which will “grow” on screen until it disappears. Similarly, in the very first screen with the “iPhone” brand, a new “i” icon lets you see the IMEI code of the device. You’ll have to provide iPhone with your Apple ID after the setup to access Springboard, whilst beta 1 allowed you skip this process.

Things which you should remember here:

• iTunes 10.5 beta 1 won’t work with iOS 5 beta 2
• iMessage seed 2 will be unable to communicate with iMessage users on seed 1.

Talking about the changes Apple made in this new beta 2, a lot of developers are posting their result on the web, some of the major changes are :

• OTA updates have been released, though none are currently available
• iCloud has a new logo in the Settings.app
• You can now backup to iCloud or the computer when setting the device up
• If no notifications are available, Notification Center shows the text “No New Notifications”
• Stock widget in the Notification Center is now off by default
• Stock wallpapers are back, but are the same that were in iOS 4

Notification System on lock-screen has been modified a little, it now stacks notifications on top of each other yet making only the latest one visible as a “bubble” in the middle of the screen. Let’s suppose you receive a  text message, the notification appears in a bubble like on iOS 4. As soon as another notification is received, the previous one goes to the top of the lock screen and is accessible by dragging down from the top of the time area. The new notification is shown in a bubble again.
