If you go to the Telus site now you will notice Blackberry 8830 already posted but without a link to buy. Fret not, for that comes tomorrow.
Useful site Mobile In Canada reports that Telus offers 50% of reduction for the duration of the contract chosen on the international transfer of data. This is especially relevant for the BlackBerry 8830's dual-platform worldwide compatibility. I'd agree with Mobile In Canada that frequent international travelers would be the ones most interested in this plan.
