The FCC has two different versions of the Milestone GSM Droid. They have the following FCC tags: IHDP56KC2 and IHDP56KC5. I want to buy the IHDP56KC2 because it has a much lower SAR rating. If anyone can help me tell the difference between them I would greatly appreciate it. IHDP56KC2: SAR 0.57 W/kg for head-adjacent use and 0.49 W/kg for body-worn use IHDP56KC5: SAR 1.10 W/kg for head-adjacent use and 0.89 W/kg for body-worn use [IHDP56KC2 and IHDP56KC5 are both links to their own FCC reports if anyone is interested in viewing them] EDIT: I figured out the difference The C2 has WCDMA 900/2100, GSM 850/900/1800/1900 The C5 has WCDMA 850/1900/2100, GSM 850/900/1800/1900 So the one being sold on expansys is the C2.
