£420?! Why are these so expensive?!
I just bought a THL W100 for £140 brand new off eBay. 1.2GHz quad core, 1GB RAM, latest unmolested version of Android JB without 3rd party garbage, gorgeous vibrant IPS display, 8(12)MP rear + 5MP front camera that takes great pics, dual sim ability, and two batteries. Thin, good weight to it, rock solid build quality.
Feels fast to use as well, very responsive. I'm really happy (and surprised... was taking a massive punt trying one of these unfamiliar foreign phones).
If cheap unfamiliar phones are this good and big-brand phones that pricey I doubt I'm ever going to buy a phone from a service provider again. Certainly not these big brands anyway.
