Its epoxy resin, look on well known auction site for remover, heat with small tip iron works well, also small craft knife helps (carefully, lol).

Any trustable source for 3GS power module?? I got some pcs from Byeforapple but most of them didn;t work.

I know this problem! I bought sometime 50pcs. only 4 worked!! Money: bye bye!!!

I had a trustable source, but my contact person was fired from his boss....now i have another source, but very expensibe (about 56$ / pc).

A good tipp: Buy only Chips in the black original packing. then you can be 80% sure that they are ok! All bad chips are packed between 2 transparent plastic foils.
