- Enter the preference name: general.useragent.override, enter string value: BlackBerry9000/4.6.0.266 Profile/MIDP-2.0 Configuration/CLDC-1.1 VendorID/120
Then you’ve done.
In above example, “BlackBerry9000/4.6.0.266 Profile/MIDP-2.0 Configuration/CLDC-1.1 VendorID/120″ is Blackberry Bold user agent.
Common user agents
iPhone user agent:
Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A543a Safari/419.3
Windows mobile 6 user agent:
Mozilla/4.0 (compatible; MSIE 6.0; Windows CE; IEMobile M.N)
In case you want to get full desktop power back, just select the settings you just added, and select “Reset”
