Sorry. I got fed up with my son not being able to plan plants vs zombies and decided to try the speedmod kernel. It's supposed to be 'safe' and it 'sounds' fast ( lol). So I incurred the dreaded triangle and did it. Went painlessly and now plants/zombies works. Weird huh?
So I'll see how the battery does on this. THEN I'll give that trick a go. honest
Anyone else could have a go at it too. Just tell us all if it works

I'm actually not 100% convinced my phone was 100% 'normal' after what I went through with the ICS update anyway, so there may have been some kind of kernel/rom conflict going on all along anyway. I dunno. Good luck everyone on getting it how you want it.

EDIT: OK So apparently I am the last person on the earth to know that plants vs zombies doesn't work on ICS and everyone knows all about it already It will work for a few minutes sometimes and then just freeze.

On another note since running speedmod today the battery seems to be going down slightly faster when data turned off (maybe half a percent more per hour) and since turning data on it's not going down by much different to that. A HUGE improvement with the data on, almost as comparible with GB. Of course that's just one day of 'testing'. This might be of no use to anyone else, but on the other hand it might be of some use to one or 2 people out there who might get a battery improvement from speedmod. I will do one more day of extensive research in the field of mobile science before doing the fiddle from my previous post and see if it really does make any difference. I'll probably stick with ICS long term if the battery settles down. I'll find my son another game he can play. On the other hand it might stop him stealing it if I tell him there's no games to play on it anymore hehe
