I have the Samsung SPH-A640 (Sprint) I bought the cord from the Sprint store, and when I connect it, it automatically reads it as a modem. After painstaking hours of finding the right drivers/programs, I noticed that I at least reads "USB Connected" on my phone. The only problem is, that before it reads that, it says Handset is set as a modem for PC or PDA. No data apps on the handset can be used (e.g. messaging, browswer, downloads, pictures) What do I need to change? Is it something in my phone I need to change? Is it in my computer? HELP!!!!!!
