Review: LG Marquee for Sprint
The Marquee runs all the stock Android 2.3 messaging applications, and doesn't offer anything new, not even from the Sprint ID packs.
It has the generic email app for POP/IMAP/Exchange email, and the dedicated Gmail application for Google users. Both of these applications are capable and time-tested.
The stock SMS/MMS app is loaded on the Marquee, and I didn't notice any different or unusual behavior with it. It offers threaded conversations, as always.
As for IM, the Marquee has GTalk on board, and nothing else. If you use Yahoo, Windows Live or AIM, you'll have to seek out third-party apps from the Android Market.
On the social networking front, the Marquee offers zero, zip, zilch, nothing. Absolutely NO social networking applications or services are pre-installed, not even Facebook and Twitter. You have to go to the Android Market and download them yourself.
