I went to Rogers today to inquire about Blackberry Data Plans and I wanted to get just the email plan for now (something liek a month for unlimited emailing). I also asked the guy about Wifi on a Blackberry and he said that if the Wifi signal is weak, the phone will automatically jump to the 3G service and therefore, if I don't have a data plan then it'll cost a lot of money. Is this true? Is there anyway that I can JUST use Wifi and not have the phone jumping to 3G browsing?
