I updated my 680. I have no use for the Push to talk, Direct push, telenav, or MobiTV so I am not sure how those work.
I did use the Yahoo messenger once just to see if it worked and it did. I cannot find out how to use mp3's for ringtones other than using Minitones. I notice a slight difference in battery management. I had hoped for more but any improvement is better than it was. My SD card is only 2gb for now so I don't know about that. ** -=[ Sharon Jean <>< ]=- >> > > Push to Talk support > Microsoft Direct Push Technology > A new Instant Messaging Application that supports AOL, Yahoo and Windows > Live messenger > Power saving enhancements > Support for larger SD cards up to 4GB including SDHC cards > Enhanced ringtone support - Supported ringtone formats include MP3, AAC, > AAC+, MIDI, WAV, and AMR. > Updated AT&T Branding > Access to Telenav and MobiTV services > > > How are the power saving enhancements?
