Hello all, I've had my family plan for years now with unlimited data plan ($30) on all lines. We have been thinking about getting new phones lately and am just curious about a couple questions in regards to not having to opt for tiered data plans. Tried a search but there really wasn't anything with a matching ques/answer. 1. If I bought a 4g phone, will I have 4g? 2. If above is no, will I atleast still have 3g unlimited? 3. For those of you who do the same as us, where do you go to buy your phone for the best retail non-contract price; brand new? Thanks.
