You should know that T-Mobile operate their 3G network at 1700/2100 MHz (so-called AWS-band), which the iPhone does not support, so with his iPhone your friend could only access T-Mobile's 2G network, which as any 2G network is relatively slow (theoretically up to 236 KBit/s which however in practice is often less).
