i got a blackberry 8310... BlackBerry Curve forum
how can you send themes to your blackberry ?
This is a little dated but should be the basics.
Theme install help.
The OTA install method is easy and fast and requires no PC or USB cables. You should use the Internet browser on your BlackBerry (not the WAP browser) to navigate to the web page containing the link for the installation.
Install using your desktop manager.
1. Download the zip file to your PC:
2. Unzip the file to a folder (name the folder).
3. Connect your Blackberry to your computer.
4. Open up Desktop Manager –> Application Loader –> Add.
5. Find the file called “ThemeName.alx” and click “OK”.
After the installation finishes, you can now change your themes by going to Options (wrench icon) –> Theme.
Additionally after installing themes keep the theme folder in the same place or the desktop manager will produce a message saying it can't find any additional applications to install in the future if you attempt to install additional themes.
Phones do have memory limits, you may not be able to keep a never ending list of themes installed. If you find that a theme does not show up look at how many themes you have installed and consider removing one to make room for the newly install theme.
Hope this helps?
