4 and 3gS back and forth

[Cap41]

Just got my Iphone 4. I put the new micro sim in. Is there any way of switching back and forth between my 3gs and iphone 4...I use Roger's as a provider.

you need an adapter, but it should work fine if you get one. You can buy one here Just to let you know that link is from this thread and I know nothing about the company.

be wary of ****** ones though - a crappy adapter could snap and leave bits of plastic in the sim tray of your iphone 3GS, which is most destructive.
