If you are thinking of installing IOS 7 as a beta version then be warned. Obviously you expect to find a few problems in a beta, but it should be more spit and polish than anything major that is needed. I found this to not be the case with IOS 7 Beta 2, firstly the install of IOS7 failed requiring me to go through the process twice for it to complete.

When I attempted to restore my apps and settings, the majority of apps failed to install, 207 in total. This backwards compatibility is an area IOS has never done very well.

Then when I tried using some of the major apps, some would crash, the graphics would screw up on others or they would become unresponsive and require a full  reboot of the device.

Thankfully I only use my iPad for fun and not work, otherwise I would be mighty disappointed, and I certainly won’t be upgrading my iPhone until IOS 7 is in final release.

My personal opinion here is that it was not ready to be released just yet, I would have liked Apple to have ensured it was a far more stable product first.
