If you have a Blackberry device that is connected to your company's BES server it may cause some issues with Thwapr depending on certain access rules.

Generally, you should be fine, but some issues that have come up for other Thwapr users are:

- SMS text message notifications from Thwapr's shortcode 757575 are being blocked by BES.

- Streaming video blocked by BES.

There may be other cases so please contact your IT department if you come across an issue that you think may be related to BES.
