Vodafone is not a Browser

"Vodafone" is not a Browser but hides the right ones.

e.g. "Mozilla/4.0 (Vodafone/1.0/LG-GU280/v10a Browser/Obigo-Q7.3 MMS/LG-MMS-V1.0/1.2 Java/ASVM/1.1 Profile/MIDP-2.1 Configuration/CLDC-1.1)"

resolved previously to "Vodafone 1.0" but is an "Obigo 7.3"

This PR corrects this.
