I'm currently on a plan I went to in May 2013. The plan is "Data Double 35(BB)" which is $35 per month. I want to switch to a Blackberry Q5 from my Blackberry 9320 using money I have accumulated in my tab (about $55). My problem is I have heard mixed reviews on the Q5. My questions are three. One, can I switch phones and keep my current plan? Two, if I try and do not like the phone, can I return it and do I get the tab credit back? Three, if I return the Q5, can I go back to my 9320 and my current plan? Thanks for any help you can give.
