I started looking for those with colourfull screens, cameras, and then I finally start seeking those PDA + phone.
Why a PDA?
There aren't many reasons, there's some stuff I did want to support:
-> A camera (just for kicks, snapshot mostly)
-> A spreadsheet - come on .. it's always usefull and keep you up of you'r expenses. Is the sort of thing everyone eventually uses for keep track of the money but always let it loose accuracy for using it less.
-> A good schedule to keep me up to things - a computer is usefull, but it doesn't fit your pocket
-> A SSH client (might be usefull)
Why NOT a PDA
Then I thought... today with java applications I can gather all those features in a mobile, and for less money :D
Some weeks from there I noticed that theres a mobile phone that assembles all the resorts I requested: Sony Ericsson V630i
-> 3G
-> micro SD card (256MB)
-> Schedule (outlook sync)
-> bluetooth 2.0
-> Camera 2.0 MegaPixel
-> java support
-> ...and other stuff :)
Since the day I bought it I tried to personalized it the most: I downloaded a lot of themes .. and spent some money in the process.. but I don't regret it, after all I've found interesting stuff.
Let's get the applications to work!
About java in mobile phones
Theres an acronym that tells the most about the Java Virtual Machine: the MIDP. For now, it's in the mobile phones market the standarts MIDP-1.0 and MIDP-2.0
MIDP stands for Mobile Information Device Profile and the differences bettween 1.0 and 2.0 differs mostly on the support to some features of the device
from http://www.nec-mfriend.com :
The Mobile Information Device Profile, or MIDP, was established by the MIDP Expert Group (whose members include Sun Microsystems, Motorola, and Nokia) as a standard Java specification to work with CLDC* in handsets, PDAs, and other mobile devices. MIDP applications are called "MIDlets," and many of these MIDP-based wireless Java applications are being developed.
According with a wap site (twilight zone), the informations follows:
Browser: Sony EricssonV630iv/R1CE
Browser/Net-Front/3.3
Profile/MIDP-2.0
Configuration/CLDC-1.1
IP Address xxx.xxx.xxx.xxx
Until now I havent find a java spreadsheet... yet! but I had more luck about sshclient
The last struggle: put a ssh client on the mobile phone
The program is the midpSSH, built in java, by Karl, available in http://www.xk72.com/midpssh/ in both MIDP 1.0 and 2.0.
So, once discovered, I downloaded the full package in MIDP-2.0 and started to use it.
First Attempt
Unfortunately, i'm unable to connect, I got a connection error "Writer: Access is Denied" and the application seems to freeze.. but it's awnsome to see the shell running in the cell phone! :D
The problem is related to the use of a special socket that is required to proceed to the connection, which is denied due to security reasons.
The issues are related to permissions of the java applications in the mobile phone. Some phones let them acess completely the outside world, others, like my own, for security reasons, of course, are quite annoying in that point.
Searching a bit, I found out another release: the midpSSH-ALPHA wich provides the possibility of connection to a middle point proxy in order to get access to the specific socket. Unfortunatelly at that moment I hadn't internet available or administrator rights in the networks I use.
A not-so-short break
Meanwhile... I reported a "handicap" in my mobile phone: 2 dead pixels on screen!!
so.. It was taken from me for repair for about a week and a half.
When it came, I finally got internet at home, and with that, *some* administrator rights in the network!
Proxy server downloaded and logistic matters solved
midpSSH-ALPHA installed, and configured,
proxy server application downloaded, ports open and running!
lets give it a shot...
Proxy server downloaded and logistic matters solved
proxy seted in persistent mode
connection to the proxy, runned OK, but the connection falls few seconds later.
changing proxy parameters to transient
connection to proxy ok, authenticating, good :D I got a shell!! unfortunatelly, few minutes later the connection is lost... "Cannot connecto to the socket", it blames!
But it's suitable for now
