Tom,
Looks like era.pl max data package is 500MB /month and 12gr for each
100kB. So you're talking about 16MB/day (or 128000000 bits/day) to stay
within the package.
HTC Hero has support for SQLite
(
http://www.devx.com/wireless/Article/40842/0/page/1) so you can store
your data on the phone. It also has Bluetooth, WIFI and USB. Naturally
I would choose WIFI to sync data from your iSeries to the device. So
your mobile app would need sync functionality when @home. It would
connect to your LAN and talk to an internal Web Service to retrieve
updated data. To speed up the sync process you would need to somehow
implement record versioning so you're only updating new data. One
downside is that hero doesn't have a keyboard.
This sounds like a fun project.
Chris

Guys,
I understand all advantages of using Web App instead of native Mobile
App.
I think about native app because of one main reason - connection. Poland
is not like US with GSM range ... our salesman will work (maybe not
often but still) in such places where mobile phone havn't access to
mobile web, however they still have to work. How to resolve access to
ERP system without access to GSM? Web app rather not support such issue
... or maybe am I wrong?
About fragile - yes, Hero is delicate ... but CEO say that we havn't
money to buy "hard" devices ...
