Dunno about superbrick, but I did read that 4.04 is out and being rolled out right now. I might give it a go, as the speedmod kernel, although slightly bette,r still gives rubbish battery life on stock 4.0.3 ROM. Left data on all day today and the same scenario occurred where the battery just drained like a drainy thing. Slightly better than with stock kernel/stock ROM but not a lot of difference really. I haven't tried the fiddle with airplain mode yet. Will try it tomorrow and see if it really works, or even makes any sort of difference at all . By the weekend there might be reports of being having bricks from updating to 4.04, OR people saying "wow this is great, the battery lasts for a whole year".

So, anyway, where do I go to collect my Nobel Prize for research in the field of mobile phones?
