I tried posting a similar question on the Technology Forum and I got a few helpful replies, but there isn't much traffic there so I'm going to try asking here.
My current phone (a Samsung Anycall that I can't stand) is in the process of dying (strange screen problems and I'd rather replace it than fix it because I hate using it so much) and so I've decided to buy a used phone and put it on my current month-to-month contract with LG.
I went into 3 different LG stores yesterday in my little city and they're all pushing smartphones. I've decided against getting a smart phone because I rarely use my phone and so it's not worth spending all that money to me once you total up the price of a 2-year contract.
I asked some of my (adult) students about where I could find a used phone in my city and they couldn't help me, so I figure the next time I'm in Seoul I'll pick one up.

Ideally, I'd only like to spend 50,000 to 100,000 won, and I want one that is easy-to-use and fairly intuitive.
1) How can I tell if a phone that I'm looking at is compatible with the LG network?
2) If I just want to go to one area, where's the best place in Seoul for me to go in terms of selection and prices to find used cell phones?
3) I don't follow cell phones at all, so do you have any recommendations for any user-friendly brands/models worth checking out (or avoiding)?

Thanks

Might be worth checking out LG again, some used phones are ridiculously priced but I found one in LG for 40, brand-new. Ideal for a Top-up phone but you should be able to just put your current sim in.

The huge electronic store at Yongsan station sells used phones for cheap. It's located right next to the subway, and I think it's on like the 9th or 10th floor. You'll see it, they only sell phones on that floor. Over there they have a used phone section.

Thanks for the suggestions. I'll hit Yongsan and find that store and I should be able to find something suitable there. I'll also stop in to any LG stores I see along the way and maybe they'll be able to hook me up.

Does anybody know where I can get a decent used cell phone in Busan?Im also looking for a pre paid or contract deal if its terms are reasonable.I don't really use my phone for long phone calls.Any input is appreciated.

Can I buy a used Lg ex contract cellphone and then use it on the Lg network with a pay as you go system or a month to month system and how costly is this?

Have the prepaid phones changed in the last year? Too bad, I amkicking myself for not saving my old phone ( Oh well, they proably wouldn't have been able to reactivate it anyways).
