My battery overheated about 10 days ago (just like another post, they acted like they never heard of this). They sent me a new (refurbished) Curve, forgot the return mailing label. Regardless, I can not access the internet with my new phone, I receive an error that this is a wi-fi service, please ensure you have an active wi-fi connection. I have called twice and been into a store 3 times since I received my new phone 5 days ago. I have turned on & off wi-fi, I have removed the battery to reboot, what else can I do? The service reps are telling me that my employer needs to handle this since I have my corporate email on it & that is to blame, but my IT department has assured me that it's a verizon issue and no one else in my company is having this issue.
