Starting next Wednesday, August 6th, T-mobile will be giving new users of the T-mobile Shadow or T-mobile Pearl, a free 30 day trial of the $19.99/month unlimited E-mail and Internet service. You heard that right, this is only for customers that purcahse a Shadow or Pearl after August 6th. Now here is the kicker; you must remember to remove this service after 30 days if you don’t want it, or your account will automaticly be billed the regular $19.99/month that the Blackberry E-mail and Internet plan costs. This is not automatic either, customers must opt-in when purchasing their new Shadow or Pearl to get the 30 free trial, otherwise? No internet for you! So what do you think? Not enough Shadow and Pearl users getting the $19.99 add-on, or is T-mobile trying to move through these devices so they can replace them? Sound off in the comments and let us know what you think.
