I have just got a blackberry curve acouple months ago, and up until now i have been able to click on a web link and select it, like if someone sends it to me in a text or email. Now my phone will not highlight the web address, and I cant access it. How do i get my phone to select it agian?

When you send over bluetooth on a blackberry and the handset pairs you need to select the file type you are send and be in the folder to received. Once in that folder you need to click the blackberry key and select received via bluetooth.

how come i carnt stream videos on my bb curve 8520

Hi! Can you please confirm that you've subscribed for BlackBerry data plan? For your information having an unlimited data plan will not entitle you use browser in BlackBerry device. For browsing in BlackBerry device your SIM card need to have special APN blackberry.net.

If you already have BlackBerry data plan then

go to Options -> Advanced Options -> Host Routing Table -> click Menu button -> select Register Now

or

Click Alt button and click Menu button -> select Show All. Look for the Internet Browser icon there.

just activate bluetooth on both phones then go to file u want to send via bluetooth, click on options then send viz bluetooth, click on search for new devices, select device name for phone u want to send file to then send.

To block calls on your Curve: 1)In the phone, press the Menu key 2)Click Options 3)Click Call Barring 4)Highlight the call blocking option you want 5)Press the Menu key 6)Click Enable 7)Type your call blocking password. To stop blocking calls, highlight a call blocking option, click the Menu key and select Disable. Please note that call blocking is not associated with your device, but instead with your carrier and your SIM. You will need to contact your service provider to purchase/enable call blocking – they will provide you with a password for the set-up listed above (which, by the way, I lifted directly from my Curve – must give credit where it is due!). Hope this helps!

Most likely this is a memory issue.  Go in to your options and advanced settings to check for available memory. Remove programs you do not use.  I am posting a link below that will help you free up memory.

You can't. To send pictures or other media, you must use the MMS (Multimedia Message Service) option. Just use the option menu button in the messaging application and choose Compose MMS. After selecting the recipient, click the menu button again to add things like pictures, videos, etc. to the message. Note that sprint includes the ability to send media in your data plan, but your recipient may get charged for the message. Some carriers, even Sprint, don't include MMS in there unlimited messaging plans but rather expect you to send the picture as SMS which the Blackberry Curve can't do.

All you have to do if u have this problem, is turn phone off, remove battery. This will reset your phone!!! And it will fix this problem.

you need the multi media package

I'm sorry to say that it is likely completely gone.

I've never heard of a Blackberry recovery service. Perhaps send an email to RIM (Research In Motion) and ask? If your BB came from your company (as opposed to a personal plan) perhaps your IT department can help?

One other thought: If you are using the BB at work and it's hooked up to a Blackberry Enterprise Server (BES) then at least your email, calendar and address data _might_ be stored on the server. Ask your IT department.
