Privacy in cellular devices


Submitted by marcin on Tue 05-Jun-2007

This article will contains various comments about privacy connected with cellular devices (in GSM networks)...

First of all, I must say, that you don't have something like that. Each time, when phone exchange data with operator stations, he know phone and SIM card details. If you have bought SIM card with concract, he know you personal info too. Of course this is not 100% reliable (phone can be not used by owner), but... This location data should be secret and the most often are. But now always...

Evolution or revolution ?

We had this topic visible here few times. I want to return to it again.

Let's show few things. First Microsoft. Do you remember problems with joining two Windows families (one started with Windows 95 and one with Windows NT) ? We had Windows 2000, which wasn't the best for users, but finally company released Windows XP and it was big success. Now we hear about Vista incompatibilies and part of reports say clear - because of it may users won't be interested in getting new OS for longer time.

Do you know what ?

Michal speak about new API for Gammu and I have new idea too ;-). Currently MMS can have many files inside. Let's make decoding SMS using the same stuff.

Do you want to have text inside ? Add one "file" with "text/plain" MIME type. Nokia Smart Messaging bitmap ? One "file" with bitmap/gif... etc. etc.

I have problems with GPRS Online in my Nokia phone (Series 40, not Symbian)


Submitted by marcin on Sat 15-Apr-2006

In first Nokia phones with GPRS (like 8310, 6310, 6310i, 6510, 3510 and maybe some other) phone was able to display "G" char instead of char displayed below network level. It was clear, that phone is in continuous GPRS session and downloading some data won't be connected with starting new session (in many networks connected with new money for operator). If phone end GPRS session after leaving WAP browser or data connection (no "G" char), it had disabled continuous GPRS sessions (it was done for example after upgrading firmware in service). Simple "gammu --nokiasetphomenus" "repaired" it.

My comment to http://blog.cihar.com/archives/2007/05/15/why_do_people_buy_non_document... :

you are generally Michal right. Well documented hardware = less problems...

But: very often people buy, what they know and what is compatible with their other hardware (like memory cards). Sometimes not well documented hardware is much better than documented. I remember times of Nokia 3310. You simply didn't have cheap and so good phone...

Życzenia 2011


Submitted by marcin on Tue 20-Dec-2011

"Moim największym marzeniem było zbudować stabilną firmę, w które ludzie będą chcieli tworzyć świetne produkty. Wszystko inne schodziło na drugi plan. Pewnie, dobrze jest mieć zyski, bo to właśnie pozwala robić świetne produkty. Ale motywacją były właśnie one: produkty, a nie pieniądze."

"Niektórzy mówią: "Dajmy klientowi, czego chce". Ale to nie jest moje podejście. Naszym zadaniem jest ustalić, czego klient będzie chciał, zanim tego zapragnie. (...) Ludzie nie wiedzą, czego chcą, dopóki się im tego nie pokaże"
