I just broke my 500Mb, and without even trying. In previous months I was restraining myself to not break it. I must admit 6Gb seems over-the-top, though.
Good idea the retention plans search, I'll try it. But yes my best bet may be with the iPhone 5, I guess.
They'll give you 6gb no problem, aslong as your account has been open for more then 90 days, If anything, mention that TELUS offers 6gb/30
Market competition has forced the whole HUP concept, so unless you don't need data for the next three years, or plan to travel, take advantage of it and put the $500 savings in your pocket.
