Gu87//GD87

Whats the difference between the 2 phones. and will all GD87 work for GU87 and visa versa. Because i see a lot of GD87 rather then GU87 just a question.

there's not a difference really... the GD87 is what the phone is called in most other countries except the US, where it's known as the GU87...But they're basically the same phone
