BlackBerry Curve 8900
Deleting multiple messages on BlackBerry
1. Highlight the date bar in the folder and click menu, then delete prior. It will delete everything in that folder prior to that date,. or
2. Hold caps lock and highlight, click menu then delete messages.
Hope this helps clear up some of the 'cons' people are throwing out about the devices.
the only thing i can think of is people selecting messages that aren't in a row, so the holding caps lock wouldnt work. but an idea i had is if the person wants to just delete messages from one person: use the search function, type in that person's name...and boom you'll see all the messages to/from them.
