I'm getting near the upgrade point on my Rogers cell phone and want to get either a Blackberry or i Phone. My current plan is only $10 per month voice and $15 add on with voicemail, lots of texting and unlimited mobile browsing so I would be sad to see that cheap price go for so many features. I'm wondering if I was to buy a blackberry outright then could i keep the $10 per month voice plan and just add data? Anyone have any advice?
