This may be a stupid question but why does some apps work on some peoples phones just fine when they install them and other people can't get them to work at all or need fixes? Some people just install programs right off the installer and they work perfectly. I have been trying to jb several times for the last few weeks when ZiPhone became so easy and I am having so many problems getting apps to work properly. Especially Summerboard and Customize (which doesn't work at all for me). I keep losing sound after installing certain apps. Especially if I install Community Sources. I was just wondering why my phone wasn't responding to jb as well as others.
