In all seriousness if you're hosting that much, pulling that much bandwidth you must have users, if you have no revenue plan right now then you probably should give up, $1500/month (or a lot less if you take some of the other examples here - S3) isn't a lot and if you can't start a business with such meagre overheads then you should probably do something else.

Eh? I haven't bought a locked phone for years... I think you meant to say "Pretty much all basically free phones given away by the networks because you're getting locked into a 12 or 18 month contract are sim-locked".

I get all my phones from places like Expansys who sell a complete range of sim-free phones.
