I personally think there are better qwerty phones out there. Can you give us a list of what's important to you? Pick your top 5 most important things from the list below and put them in order of most important to least important.
Monthly service price (and what kind of service you need, like 300 minutes of voice, unlimited data, unlimited SMS, etc)
Cost of the phone itself (cheaper with long term contracts like a 2-year contract)
Big qwerty keyboard, easy to type on
Big screen to read
Long battery life between recharges
Email
SMS
Web browsing
Clear phone service
Coverage / reliable phone and data service everywhere you go
Good customer service
Cheap warranty/insurance
Free/cheap downloadable programs
Instant Messaging (specify AIM/Yahoo/MSN/Google/etc)
Either list them all in order, or pick your top 5 so we know what's most important to you so we can recommend something better than the Blackjack.
