Get back to basics
If i can receive all internet access on my cheap w200i i'm sure you'd have no probs.
Image quality is sharp and pretty fast on my regular lap top, and a seven day bundle for a fiver is cheap in comparison, also no contracts, no direct debit rubbish, just top up on the phone as you would for calls.
Recommended this to whiteladder, for him just a matter of changing phone companies.
Give Orange a go, might save you a lot of grief.
