has anyone tried one of those internal antennas? i'm thinking of getting one and was wondering if anyone has seen a difference useing one.

I put one of those little stickys antenna booster on the siearra chip close to the antenna an it still didnt improve the reception.

I don't even use mine as a phone that much anymore.
I keep it in my car as a GPS now.

Those plastic sticky antennas are fake and fraudulent. The FTC has ordered many companies to stop selling them. If you see a retailer selling them, report them to the FTC.

All that is on the plastic is a 'picture' of an antenna. The ink used isn't even conductive.
