I have seen alot of you looking for a nice case that is designed for the Pearl AND will put it to sleep when inserted.
I stopped in my local T-Mobile store this weekend and they just got this one in. Its a VERY nice case, magnet closer, thin, light, all leather and a nice belt clip - but here is the STUPID thing - you have to insert the Pearl UPSIDE DOWN for the magnet to touch the area on the Pearl to put it in sleep mode.
Dont ask me why - but that is how it works. I bought it anyway - but its a pain when the phone is ringing and you pull out your Pearl and its upside down...but it does fit the Pearl perfectly.
The SKU number is SUPA00550 and it cost $19.99
