Hey I have the same question. I have the sidekick id right now and I want the gravity. It really depends on what you want in the phone and what you will use the most. The sidekick id has internet browser that is awesome and great aim. But the gravity has a camera, video , and voice recording They both have aim and text messaging I personally think the gravity is better but its really your opinion

Here are some reviews and you can see more about the phones.
(The Samsung gravity got a higher rating in the review)
That was great advice. I think you should get the samsung gravity. What my granddaddy says is to always get a new phone at the end of each year.
Yea i don't think that is Right (The phone part not ur grandad)
I have the samsung gravity and i HATE it with a capital H it's an okay phone for the first few months but then it SUCKS it gets sticky and dosnet work correctly.!
the slide is better because i think you can take pic and stuff. the only thing that is better on an id is that you can change the skins. i had an id and i hated it. i switched to the lx
how to unlock a sidekick id
samsung corby s3563 has wifi as well but id still say the samsung corby is better

No a sidekick does NOT have a camera! We don't know why.....

tmobile
You keep the phone inside.
No.
yes.. i would like codes for my sidekick i.d!
Sidekick black and white was the first. It was followed by sidekick color, sidekick 2, sidekick 3, sidekick ID, sidekick lx, sidekick slide, and finally sidekick 2008, and the new sidekick lx 2009 is coming out very soon
