Swapped trackballs with an old Pearl and all seems fine now. I set my horizontal sensitivity back to 70 and see no issues yet.
I did it myself with a T7 torx-driver and a credit card. Be CAREFUL if you try this! I almost broke the little tabs off of the top earpiece cover.
Yeah, I guess my warranty is in the toilet...
-BTW: The black Tour trackball seems to work just fine in the Pearl...
I'm still not totally sold on the Tour I guess. I miss the size and convenience of my Pearl.
?? Why couldn't they just make a Pearl with more memory??!!
(you'd think I've never seen smilies before eh?!!)
