iPhone 4 does not wake up from being locked My iPhone 4 periodically does not wake up from being locked. I have to wake it by holding the home and power buttons. This is happening a lot more frequently as of late than before. It has the latest OS. It seems quite a few people have the same problem. Does anyone know a solution to this problem? None that I found on the Apple forum seems to solve it.
You could try going by the Apple Store to meet with a Genius (if there is one close enough to you). They have diagnostics they'll run for free to see if something weird is going on with your phone. Make an appointment online.
