downgrade
I bought my iphone 4 this year, its the perfect phone that i ever have. But something happend this week
Since I upgrade to ios 7, my iphone 4 become so slow, Some of the app cannot work any more.
The funny thing is that I cannot downgrade to iso 6 any more.
I trusted apple so much, and i upgraded ios 7 without thinking, but it didn't make phone better.
Can you help me to "upgrade" my phone to ios 6 design by Steve Jobs?
iPhone 4, iOS 7
