I just ordered my first cell phone EVER! An unlocked Nexus One HTC. I have so many questions, I don't know where to begin. Here's my plan. I'm cheap. Very cheap. I don't want to actually get a voice plan, I just want to get a data only service, and use it for tethering and VoiP. I already have a VoiP plan I use on my home phone, so I was thinking I'd use sipdroid. As for service, any recommendations? I want the least jack-assy carrier with the best value data only plan. So far it seems T-Mobile is in the lead with 40$/mo unlimited. I doubt I'd ever break 10Gb/mo, so if anybody knows of anything better, I'd love to hear it. Also, I'm guessing voip and tethering are both breaches of contracts with certain carriers. Any tips, suggestions on who to avoid if I'm planning on doing this, or any other sage advice? Thanks!
