hey there, currently working/ going to school in mexico, i just bought my lg gd900 crystal, and have noticed even if i only recieve one text everytime i go into messages it will say not enough usim memory, please delete messages. i then go into settings and look at the memory info and see that i am only using 3kb of 172kb....but if i click on the box for more info, it shows that i have 20/20 txt messages, im thinking that maybe this has to do with the card they gave me not being sufficient for the phone? but then again i dont know much about these things.....some help would def. be appreciated. thx
