iPhone 3GS Crashes (gets Black Screen with White Apple Logo) Mid Phonecall
After a while, the phone comes back on, I’m not required to enter my SIM Pin and everything seems to work fine(ish) from then onwards.
I have done a reset, restore and resync in iTunes, but this still happens.
It does not seem to matter if the battery is 100% charged or not! I have tried a few battery recalibrations too!
I’ve also noticed a slight sluggishness since the upgrade to iOS4 (for example, when you receive a text message, click to view, there is a noticeable delay where the screen is blank (you can see the lines where messages should be) and then they appear/message opens).
Any ideas?
Cheers in advance.
