Sounds like Multibit or Electrum would do what you need, worth checking the android wallet too (Bitcoin-Wallet). Know what you mean about the blockchain, I only had 3g available here for a long time and it took me a couple of months to get the blockchain up to date with the monthly limits.
Thanks! I will have a look at them.
Going to keep an eye on this as it definately has potential to be transformative technology.
