I've been lurking around for a while and have greatly appreciated information on here about flashing firmware on the i7500, so thanks for that. I do now have a weird problem with my Galaxy. A buzzing in the earpiece has appeared. More precisely, it's not a buzzing that happens all the time, but only when there is a sound - it's really distorted. I can hear it immediately when I make a call, it's really obvious on the ringing sounds. It makes it really hard to understand people. First I thought that it had to do with flashing to IK5 as it appeared around that time, but I have since tried both IK4 and JC6, and the issue persists. My guess is the speaker is broken / breaking, and it's a case for the service centre. Thoughts? Thanks in advance for any help.
