On the subject of Mobile Substrate, my phone has been constantly going into Safe Mode since i did the first update through cydia. It seems to have gone now (since another Mobile Substrate update has come out). I'm sure i received 2-3 updates.
Has anyone else suffered from this..? I only assume some others have due to updates coming out so soon.
I'll stick to what other people suggest, which is to switch your phone on and off daily to keep things running smooth etc. I wouldn't like to guess why your batt % gets stuck..
As i mentioned above and where others have mentioned in other threads, i believe that when you use icons of a dynamic nature (moving etc), i think it causes the phone to crash or act weird. I had a live clock, i think this was the problem. So i'm going to re-load it and see if it was infact the clock giving me the issues.
I don't think you have problems with your substrate either. It'll be something silly. If you think about it, your own mobile substrate protects itself from itself.. how irish does that sound. I can't explain it better without further research.
