Hi guys I got a cellphone about 3 months ago.. and now it's my birthday.. I'm 17 years old and I was checking out cool keychains and Iv'e seen some people with cellphone keychains... now I looked on my phone and it's a A737 AT&T samsung model phone a slideup phone I guess you could say and I don't see anywhere on that phone where to hook the keychain... and I was wondering are there some cellphones that just can't get them? and if so could you guys list cheap cell phones I could buy to do that..? Thank you guys
