poor data connection

Ive had a legend for a few weeks on a vodfone contract, I cannot connect the browser when im away from my wifi, ie through vodafone 3g, it seems non-existent, there have been a number of posts on the vodafone forum about this, which seems to suggest the aerial in the bottom part of the phone doesnt connect [rpperly, but i dont know why this does effect voice calls, which are all righ, does anyone alse have this problem??

I have the same issue
Legend cant browse internet via some access points with B 11 Mb it connects gets address, but nothing, and it is not switching to mobile internet because it thinks it is connected via access point but then I discovered, in nights when all other devices is turned off it gets e-mails, and when I came very close to this access points to browse internet- it works - about 1 meter, while on other 54G it works 100 of meters even further than PC, so it is packet settings in OS.
