White Screen :( :(
First off. I have a 3gs with 4.01 jailbroken software.
For the last week I have been getting a black white screen when look at my phone. It doesn't happen everytime but it happens 15x a day at least. The only way to get back to my regular screen is hitting the unlock button numerous times until it finally shows. I haven't dropped it lately and only once in the past. Is there any fix to this?please help because this is really annoying.
