Samsung Focus & iPhone 4

[cc3d]

I currently have an iPhone 4 and I need to get a Samsung Focus for app development on the Win Phone 7 platform.

If I get a Samsung Focus (off contract), can I use my iPhone 4 sim (with adapter) in the Samsung Focus?

If I do this, will ATT try to hose me up for having an alternate phone on that SIM's service occasionally?

related question: Could I just use the Samsung Focus for development purposes without ever putting a SIM in it?

thanks for the help.

I don't see why u would have a problem...when I had my 3gs I used that SIM on all kinds of different phones even non smart phones...only problem I had was the txt to other phone from the voice mail setup the iPhone had....weird txt when I got a voicemail and one after I deleted it....other than that all else was fine.....also im sure u could use the focus without putting a sim in....seems to work fine for me without one

Nope - no problem. Go ahead and use your SIM...it's tied to your account/subscription - not your device.

The beautifully designed Apple iPhone 4 is currently the smartphone to beat, improving the spec of the old 3GS model and upgrading key specifications. Specifically, the 4th-gen iPhone debuts the iOS4 software, which adds features such as multi-tasking, 'FaceTime' video chat and HD video recording and editing.
