HERO/sero: bunch of BS!

[pjrey]

my brothers phone broke, an old razor.. so after being a sprint customer for 2 years (on the sero 500 plan) decided to upgrade (two year discount, and web discount) got the phone, and cannot activate it.. after 5 days of trying, some saying its possible, others saying not.. idecided to look into this for him. what a bunch of crap.. they do not allow the htc hero, the instinct, or the palm pre on the sero plan.. ok great... but WHY? really.. WHY?? i called and asked.. and talked to 5 different people.. all had horrible excuses (reasons).. because it requires the high speed data plan was one response, another was because the data plan is much more intricate(???)! wow...as far as i know there is only one data plan! my brother has it... why cant he use the hero on his sero plan? its a scam to get people out of their super deal contracts and scam more money from them! so, i told him to return it.. and get the htc touch pro or touch pro 2... he shouldnt have any issues with that (im just worried they will soon put all smart phones on the NOT ABLE TO WORK WITH SERO list...
can someone tell me why the hero cannot be used with the sero plan?
what a hassle this has been!
thanks for listening!
please post back!
