you are limited to the few phones that 3 use as they are the only ones that support wcdma, I also think the New Nokia 7610 + 6630 support this network....

the other older phones you mentioned are only GSM phones so the sim will not work

This is incorrect. The 6630 IS a 3G phone but it uses UMTS not WCDMA as 3 do so the 3 sim might, emphasise the might, be able to use the O2 2g network but not the 3 3g network as UMTS and WCDMA are different standards operating on different frequencies.

you might be correct, I just assumed there was a single standard

No, Browntoa is being too polite; you are wrong

UMTS used WCDMA technology, and the two terms are often used interchangeably with each other

WCDMA is also referred to as UMTS - the two terms have become interchangeable

It is complete nonsense to suggest that the 3 sim, a 3g phone and 3's 3g network are mutually incompatible
