Hey guys ! i just got a new i7500 today and i have some questions . why my laptop/my other phone can't connect with my i7500 using bleutooth ? is that a bug or what ? bluetooth is something important to me. what means rom , firmware , galaxo and GAOSP ? my phone works with android 1.5 , i want to upgrade it to 2.2 . how can i do that ? and if i upgrade i'll lose anything or have risks ? the upgrade to 2.2 will resolve the bluetooth problems? i can't see the file manager icon in my menu ! how can i manage my files , pictures , movies and audio files ? if i browse i picture using the gallery i can't send it via bluetooth ! what's the problem? give me advices ! this is the first android mobile i use .. im a web developer! thanks .
