Rate my post up if you can because these questions keep coming up. The more ratings, the more likely we are to receive a reply from someone in the higher echelons of WIND.
WIND won't tell us any info on your questions really, except for the Tab system.
WIND has stated they will NOT implement a tab system.
Many of us want more (or at least more than 2 half decent) phones and more plans. WIND hasn't said anything to us about it, which only means these are most likely far off from arriving.
