Some more thoughts after another day with the Pearl:
I found that SMS was not working, but a 5 minute call to Cingular - which involved giving them the last 4 digits of my SIM card and turning the phone off then on again - got SMS working! Still haven't tried MMS, but I have a feeling it'll work, especially now that Cingular has fully enabled things. This particular operator did inquire as to "where" I got the phone - a little suspicious - but I just feigned ignorance and changed the subject.
I think the Pearl's handset volume is just fine, contrary to some threads on this board and 'net reviews (CNET). The SLVR volume was initally low, and I had to use a "SEEM" editor to raise it, but then I always had issues with callers hearing an "echo"... Now, callers say the Pearl sounds great, and they sound nice and crisp and clear to me as well!
The voice dialing is SUPERB! On the SVLR you have to "record" the person's name and then say it pretty much EXACTLY the same way to get pseudo "voice dialing". (And you have to record one for EACH contact.) With the Pearl, I can just say dial "8-6-7-5-3-0-9", and before I know it, Jenny's on the phone!
I'm growing to LOVE the trackball. What a great idea! So much more intuitive than a left-right-up-down toggle. And my phone has no in-pocket "missed calls" issues... (It must have a later OS? v4.2.0.42)
I got PocketMac to work for my Contacts, but my iCal won't sync at all. The contacts were a biggie, and I'm happy that worked, but I still want/need calendar sync. Hopefully soon. At least PocketMac is now FREE for BlackBerry owners through the BB web site.
Oh, and the "Dimension Today Plus" theme is awesome! Very nice. I just changed the font size to 8 instead of 9 point.
Ummm...I guess that's it for now!
