that 3G is only supported on the 2100mhz frequency. Only Three use that frequency in the UK.
Think you might of got something wrong there 
No, he's saying Three are the only company to use the 2100 band for 3G. Other suppliers use the lower bands (850mhz and 900Mhz I seem to remember?)
As the phone only uses the 2100 spectrum, it can only work on Three.
Of course you can enable tethering on your android phone, but your contract has to allow it, or they might just cut you off.

My £100 Huawei G300 does that and can be picked up from Tesco, though unless you go with Vodafone you then have to get an unlock key.
Not sure if that's cheap enough, mind.
Lumia 610 or 710. Fast, very simple and will do everything needed very cheap (far better than a similarly priced Android phone tbh).

No. All networks use 2100Mhz for 3G, some networks additionally use 900/1800Mhz if they want to offload capacity to other freqency spectrums but it's by no means common or a requirement and was only recently allowed. If they were the only company using 2100Mhz my years of testing at Orange must have been in the twilight zone.
