You need to make sure you know what you're getting yourself into. 2100 is the most common 3G freq in use globally. 2100 is not in widespread use here.
She should just get an iPhone and not worry about it.
While the iPHONE 3G is a decent device with an excellent OS, it is not the only handset capable of "true" world roaming. The SonyEricsson W760i is also tri-band UMTS (850MHz/1900MHz/2100MHz) and quad-band GSM (850MHz/900MHz/1800MHz/1900MHz) which has so far been an excellent performer in the USA and abroad.
With regards to T-Mobile USA, they are deploying their UMTS network in a hybrid 1700MHz/2100MHz configuration. Essentially, T-Mobile USA is going to use one frequency for the downlink and one frequency for the uplink. (I do not remember which is up and which is down.) So, a UMTS 2100MHz handset would
NOT be able to properly function on the T-Mobile USA network.
