Here is a list of some of SIP clients for Nokia S60. Kindly note that these are generic SIP clients and not bound to any SIP provider as such.

• Tivi – Tivi is perhaps my favourite softphone. It is available as a free download and I believe the authors intend to keep it this way. Moreover Tivi is perhaps the only softphone which can directly call an IP address without registering with a SIP provider (though I couldn’t hear the opposite person when I tried this feature).
• Fring – The main disadvantage of Fring is that it routes all SIP calls through its own proxy server. So there is latency for calls made using SIP.
• Adore Softphone – To use Adore Softphone, you will first have to register your device’s IMEI number. Then you can proceed to download it. Ascent Telecom’s Endura Mobile Dialer and REVE Systems’ Itel Mobile Dialer Express are similar to this but they are not available for free for end-users.
• Talkonaut – I did not try this but I think this works based on callback.
• s60voip – An open-source software, this is yet another SIP client to be explored. The major hurdle in using it is that you will have to sign this application by visiting https://www.symbiansigned.com in order to use it.

There are other mVoIP clients such as Truphone, O-FONE, etc. which all use the SIP protocol but they do not allow configuring other SIP providers and are bound to their services. There is a possibility though that these products may in the future enable to configure other SIP providers.

Lastly if you are likely to use mobile VoIP extensively, you may consider buying a Nokia handset which comes with a built-in VoIP client. (See References below).

Recently a salesperson turned up at our office proposing to sell Kingston 32 GB pen drives for a very cheap price (Rs.1200 each). He claimed that he had stolen some of them from the port when the shipment arrived. We were not interested and so did not purchase any of them.

As soon as he left, we did a google for the actual price of Kingston 32 GB pen drive. What we came across was a large number of articles mentioning about fake 32 GB Kingston pen drives.

These fake pen drives are actually 512 MB – 2 GB. The packing is exactly like that of Kingston. And when you copy a huge file to the drive, it shows as if the file got copied successfully. Therefore people got fooled easily. The best way I can think of to check whether the pen drive is genuine or not is to copy a huge file to it and compare the md5sums of both the original and the copied file. If they are the same, the copy was successful.

I again went down and looked for the person but he had already left. I think we have to be very careful when purchasing products which come for an extremely low rate.

Another interesting thing which reflects here is the human psychology. Below is an article reg. these fake 32 GB pen drives where almost all the employees of the company ended up purchasing it. It would be interesting to see how many of these employees would be willing to steal these pen drives (given that they would not be caught) from the shipment directly. I am sure many of them wouldn’t be willing to do such a thing. But yet they might not even had given a second thought when purchasing them even when they were told that they were stolen :).
