I had an iPod touch 4 for a month and a half, then sold it. I'll never buy again the Apple iOS and iTunes jail. Imagine I paid for those interminable limitations. It always has to be the Apple way to "hold it", Steve? You can hold it yourself, then!
apps denied by apple, previously only available on jailbroken phones...we now provide you with more options. Innovation at its finest. (Disclaimer: Some options only available on iPhone 4. Enhancements may slow performance on older models.)
To be honest, as much as I dislike apple as a company, I like that they're releasing this early. Gives them a chance to try it out on the other platforms, so they can make adjustments as required for the ipad.
