See now I've been wondering since yesterday about home buttons and jailbreaks. Once every couple of days I'll press my home button to bring up the unlock screen and nothing'll happen, I'll have to press again. This never used to happen and I recently rejailbroke.
I didn't make any connection until I saw my boyfriend do the exact same thing on his jailbroken 2G yesterday.
On how they feel, mine is quite easy to push in, my boyfriend's seems to be stiffer and have more of a click to it. We both have 2Gs, I prefer mine.
