yes there is a way.
download "opera mini" (you can google it for download sites) for internet access. however u cannot download anything OTA (over the air) from websites.
as far as texting... the device does not support texting with boost.
there are several ways around this..
you can try a free messaging program (one such as "RAMBLE IM" to use AOL IM).
i used to use this and just send messages to peoples phone numbers that i had saved on my buddylist. (EX: +15552223333)
you can download "GMAIL" which is google email and send emails to peoples cell phone numbers. every cell phone number comes with an email.. for example to send a text to a VERIZON customer u would send the email to firstname.lastname@example.org
and they would just reply to it and u would get it. however, they wont see ur phone number it would show up as ur email account u set up with google mail. another however is that gmail doesnt inform u on ur handset when u receive an email u have to manually check it and refresh it but if u go to ur google email account using a computer u can go to settings/options-> forwarding/pop tab-> and forward all emails to ur phone email@example.com
) now everytime u get an email it will send it to ur handset as well and it will vibrate or ring whatever u have it on and let u know u have a message.
you can google all these programs to download them and put them on ur blackberry thru desktop manager. good luck.
