Default T-Mobile 8320 Automatic Wi-Fi Roaming/Connection

Please Login to Remove!

Hi:

(I've searched the forums and didn't find an answer...)

I'm using an 8320 on T-Mobile using 4.5.0.52/2.7.0.66. (Of which everything has largely been working great for about a month.)

I find myself constantly showing up at locations and searching for wi-fi networks to connect to. Is it possible to get the BlackBerry to always automatically be searching for open unsecured networks to connect to so I don't have to do this everywhere?

Thanks for your time.

Jarrett

To answer your question its Yes and No. It wll not just grab an open WiFi connection to use but you can manually add a few default profiles for unconfigured routers.

Add SSID's like:

linksys
Belkin54

etc......

Other than that there is no automatic way to connect.

Thanks for the suggestion, good idea. I'll probably add linksys, Belkin54g, wireless, default, netgear, and see how it goes... Thank you again.

You will notice you will be on UMA a lot. I renamed the profiles to Open Wifi so I know when connected. So you will get T-Mobile - Open WiFi

Please keep in mind the security implications of connecting to random networks. A recent visit to the DEFCON hackers convention revealed many interesting details about iphone owners/users since its defaut config auto connects to open networks. Most users had no idea what information their iphone was leaking to some well placed open access points. It made for quite an interesting display.

I guess the good news about using a BlackBerry is end to end data encryption unlike an iPhone.

So no data snooping.

Not all BB apps use the encrypted proxy transport all the time. Fortunately most make you agree to use direct access before the get on the network. Not withstanding, even if your communications are encrypted, what does the BB expose to someone prodding it? I haven't had time to analise the BB's network profile. But as a security guy, I am always paranoid to connect ANY device to ANY unknown network environment. I like to know when and where I am connect so I can at least be alert for unusual activity.

I to am a security guy, the following are totally secure:

Voice,SMS, MMS, PIN, Email, BB Browser, BBM (Internet Profile), File System and Media Card.


Questionable:

3rd Party Apps that do not require a BB Data Paln.




As for my laptop, when I connect to a HotSpot or open connection I use VPN to make a secure tunnel first and even then I am very safe about what I transmit.

I do agree with your concern!

Another note (separate of access points) is that not all communications are end-to-end encrypted. They are encrypted to your provider's proxy. If you are using an app that accesses the web (assuming it does not use direct network access), once you pass the proxy end-point you are no longer encrypted unless the app you are using itself offers encryption.

A specific case in point: Opera mini actually proxies all https communication to a server at opera corporate that in-line optimizes the html code. So you are double encrypted to the end of your provider's (eg: Tmo) network, then encrypted to an opera server where they see your communications, they the make a separate https connection to the encrypted web site and proxy/translate request and responses.

Even the regular browser and opera in non-https mode are plaintext trasport after they leave your provider's proxy. So not quite end-to-end. Be cautious before sending that data.

Very true. I know many users think that an email is totally secure when sent from the BlackBerry when in fact it is secure fom the BlackBerry, through the carrier and to RIM but once RIM begins the transport of the email to the destination server it is out in the open.
