I have searched the forum and internet for the right solution to this problem but cant seem to find any specifics. I jailbroke a 2g and everything seems to work fine, except the external speaker. The phone gives and error about a device not being compatible. Now the speaker works with everything except game sounds and ipod external sound. ie, i can hear incoming calls, and the springboard sounds, but not the sounds from games or music. my understanding is that there are two problems with the 2g speaker. One is a bad connection with the earphones. That does not seem to be the problem. the other is a bad jailbreak, or something corrupt in the jailbreak files...because it has problems just like i described. I was going to re-jailbreak, but i thought i would find out if anyone has run into this problem and found out the exact procedure for fixing it. any ideas??
