Hey guys, I've been lurking on this site for awhile reading all the awsome iphone impressions and opinons and I can't wait to join you guys as an iphone owner in a few weeks. Unfortunately a major concern about it sprung to mind today. I'm already a cingular/AT&T customer paying the 39.99 a month so I'm planning on just paying the 20 extra for unlimited data and 200 texts, but the problem is in the texts. Some workers at the AT&T store told me that browsing the internet could expose my number to potential text messaging spammers and I would be helpless against an onslaught of spam text messages that could exceed my 200 limit and start overcharging me. I asked if there was anyway to block text messaging on the phone and they said there was no way to do it, the only option I have is to pay the 20 more extra to have unlimited texts. So my question is to all of you people who have the phone is have you had any problems with getting texted unwanted spam or messages? I'm pretty sure the people at the store were either trying to scare me and tricking me into getting the unlimeted texts plan or just stupid. Anybodys experiences or knowledge about this situation would help me out a ton. Thanks!
