I've been doing alot of searching about the samsung galexy p1000 and i love it. my mom has the version version..and pays 30 a month for 2 gig. i was looking at these. Samsung Galaxy Tab SCHI800BKV Tablet PC | refurbished Tablet PCs but it appears to be a version version. will i have to contact version to even use it? and if i could i would rather have a unlocked tablet. so i can go to what even network i want. if i got the tomobile one could i just put my tmobile sim in it? then use its calling and texting i pay for and then use the wifi for data? so much to learn with phones and tablets... and since im in the market for anything really. an unlocked phone would not be bad either. can unlocked phone work with version or a gsm(sim) network? my budget is 200 to 300 US dollars.
