Replying to: Re: no HSPA+ by mommamea
The network speeds supported by a phone are determined by its radio chip (hardware) and generally cannot be upgraded.
There have been rare cases where a phone shipped with hardware designed for a faster speed but it was limited in software for some reason (perhaps because software for the faster standard was not finished yet) and a subsequent software upgrade "unlocked" the faster speed capability.
But that is rare. In general, a phone that ships without HSPA+ will never be able to support HSPA+.
